Intercept & view all Android HTTP(S)
Mock endpoints or entire servers
Rewrite, redirect, or inject errors
HTTP Toolkit is a beautiful & open-source tool
for debugging, testing and building with HTTP(S)
on Windows, Linux & Mac.
Scan a QR code on the device to start setup, or remotely connect debuggable devices via ADB.
Reconnect again later in one tap.
Supports Android Lollipop and later (v5 / API level 21+)
No messing around with certificate files and wifi settings.
Click the button, accept permissions, start capturing traffic.
Immediately view HTTPS on any device from apps that trust user-installed certificates, like Chrome.
Enable trust in your own app with one tiny manifest change.
On emulators & rooted devices, easily intercept HTTPS from any app, with automatic injection of a system certificate authority.

Explore, search & examine HTTP
Skim through traffic with highlighting by content type, status & source, or search by URL, status and headers to hunt down the messages that matter.
Examine the URL, status, headers & body of each request or response, with inline explanations & docs from MDN.
Dig into message bodies with highlighting & autoformatting for JSON, HTML, JS, hex and others, all using the power of Monaco, the editor from Visual Studio Code.
Pause & edit live HTTP traffic
Precisely match requests, jump to them when they appear, and edit anything: the target URL, method, headers or body.
Manually respond directly to requests as they arrive, or pass them upstream, and pause & edit the real response on the way back.
Step through HTTP traffic request by request, or manually mock endpoints and errors.
Test with fully automated mock responses Pro
Create rules to match requests and respond with your own content, to quickly prototype against new endpoints or services.
Define new endpoints, override existing ones, or replace external services, to reproduce tricky edge cases and test your error handling.
Import & export your mock rulesets, to build complex setups and share them with your team.
Inject request timeouts, simulate connection failures, and silently redirect requests from one server to another.Pro
Precise matching lets you target the requests you care about. Match any requests sent anywhere by using HTTP Toolkit as a proxy, send requests directly to use it as a mock server.
And there's more to come too!
Future plans include security analysis & metrics, session-wide performance graphs & analysis, HTTP client tooling, Docker integration & more...
